220kVA Distribution Transformer
220kVA distribution transformer features: 1.220kVA transformer structure is compact, low temperature rise and noise, strong overload capacity. High quality silicon steel sheet, lower loss. 2. The box adopts corrugated oil tank full seal structure, prevent air and water contact transformer, reduce oil aging, prolong the service life of the transformer; The elastic deformation of corrugated plate regulates the volume change of transformer oil thermal expansion and contraction. 3. Distribution transformer is outdoor structure, anti-pollution level is high; no need to replace transformer oil during normal use, maintenance-free, to ensure the safe operation and reliability of the power grid. 4. The transformer is equipped with pressure relief safety protection device. When the transformer fails and the pressure is too high, it can be reliably and safely released through the pressure relief valve to prevent explosion. High-quality rubber sealing material prevents the transformer from aging or leaking.
